Background: Pulmonary arterial hypertension is frequent in patients with severe chronic obstructive pulmonary disease (COPD). It increases the morbidity and mortality of patients with advanced stage of COPD. The use of long-term oxygen therapy (LTOT) and some other vasodilators seems necessary to prevent pulmonary arterial hypertension (PAH) and right heart failure in these patients. Objective: This study was planned to compare the effect of LTOT alone and LTOT combined with sildenafil (PDE-5 inhibitor) and simvastatin (HMG CoA reductase inhibitor) on pulmonary arterial pressure of patients with severe COPD having hypoxia at rest. Methods: It was a cross-sectional and comparative study. All patients with severe COPD having hypoxia at rest (SpO2<88%) had been classified in three groups: Group 1 (treated with LTOT), Group 2 (treated with LTOT+sildenafil), and Group 3 (treated with LT..
